Thunderbolts* post-credits scene was shot during Avengers: Doomsday production

I'm glad to see that Thunderbolts* is shaping up to be the best Marvel movie of the year, and certainly one of the Multiverse Saga's highlights leading up to the Avengers: Doomsday and Secret Wars movies. Sure, The Fantastic Four is still a few months out, but I had Thunderbolts* at the top of my list when it comes to this year's MCU attractions long before the praising reviews came out.

As it's been the case since Avengers: Endgame, I knew everything about Thunderbolts* well before its premiere...
